I don't think you will have any problem finding the parts you require and you have found the right place to ask - to help identify the make of the module It would be handy if you could upload a photograph of the watch and module.
Also give details of any markings on the module itself e.g Hughes etc?
Have a look here to see if you can identify the watch on this site
